B.Tech Previous year questions of Dynamics of Machines 2012
Q. 1. An epicylic gear train is shown in fig., the number of teeth on A and B are 80 and 200. Determine the speed of arm "a".
1. If a rotates at 100 rpm clockwise and B at 50 rpm counter clockwise.
2. If a rotates at 100 rpm clockwise and B is Stationary.
Q. 2 Three masses of 8 kg, 12 kg and 15 kg, attached at radial distance of 80mm, 100mm, and 60mm respectively to a disc in a shaft are in complete balance. Determine the angular positions of the masses 12 kg and 15 kg relative to 8kg mass.
